Best 3 monitor setup for gaming

So, i'm just starting my search for a possible 3 monitor setup for gaming. I'm currently using a Samsung 27" 120Hz. I want to have the best quality I can but possibly go with 3 monitors.

If price was not an issue and you had plenty of computer to push it what would you get?

On a side note.. If my game says I can adjust my field of view up to 90 degrees and i'm running 3 monitors will I ever see more
than that 90 degrees or does it just stretch it. I really don't want a stretched screen. But, if I can see more than I can with 1 monitor it
sure seems like a nice advantage for shooters.
